3. TOPOLOGY
The computer can be connected in a network . But, in order to make
any network work properly, the computers should be arranged in a
particular manner. The arrangement of computers depends upon the
hardware capabilities of the network and the characteristics of the
various modes of data transfer. The other factors to consider while
making a network are price; type of medium used to connect computer,
future growth of the network, i.e. whether the existing network can be
modified or not, etc.
5. STAR TOPOLOGY
Star network is one of the most common
computer network topologies. In the star
topology the computers on the network are
connected to a central device called a hub or
concentrator. Each computer is connected to
the hub using a cable. In a star network data
passes through the hub before continuing to
its destination. The hub manages and
controls all the functions of the network.
6. Advantages of star topology
Easy to implement and
extend, even in large
networks.
Easy to detect faults and
remove parts.
If any computer system except
the hub crashes, then rest of
the network will not be affect
and the network will continue
to work properly.
Disadvantages of star topology
Limited cable length and
limited number of stations or
computer.
Failure of the nub van disable
the entire network.
One virus in the network all
affect all the connected
systems.
7. BUS TOPOLOGY
Bus Topology is a multipoint topology. In this topology, the
mode(i.e. computers, peripherals, file servers, etc.) are connected
through a shared communication line and this communication line
is called bus. In bus topology, there is a terminator at each of the
cable.
8. Advantages of Bus topology
Require s less cable than star
topology.
Easy to extend, i.e. a node can be
added to the network eithout
any problem.
Typically, the cheapest topology
to implement.
Failure of one work station or
computer does not affect other
system.
Disadvantages of Bus topology
Entire network shuts down if
there is a break in the main
cable(bus).
Terminators are required at
both the ends of the bus.
Difficult to identify the
problem if the entire network
shuts down.
Limited cable length and
limited number of systems
connected to a bus.
9. TREE TOPOLOGY
A tree topology shown a combination
of characteristics of bus and star
topologies. The tree topology is also
called a hierarchical or star topology. In
this topology, the nodes are connected
in groups of star networks that branch
out from a single root. The root node
usually controls the network.
10. Advantages of tree topology
Easy to extend, new users
can be added by simply
adding a new hub.
Easy to manage as the root
node provides centralized
management and
monitoring .
Disadvantages of tree topology
Entire network depends on
one node and failure of that
node breaks down the
whole network.
If the bus break, the entire
network goes down.
